@b0rk It looks like #Gitlab is doing some work on using #ActivityPub. There is a really old discussion on #Github about implementing it on #Gitea as well. Wouldn't this solve a lot of the issues exposed by the article?

Btw, I'm working on Mastic: a #Mastodon instance written in #Rust, running entirely on the Internet Computer as #WASM canisters.

One canister per user, Internet Identity auth, SNS-based DAO governance, no PostgreSQL/Redis/Nginx. Fully ActivityPub-compatible.

Live by the end of September.

FediForum Number 7 Is Happening And It Makes Me Happy

The 7th FediForum is happening right now (yesterday, today, and tomorrow). There are two a year and I love going to them.

You can follow along using the hashtag #FediForum.

Most of the talks are a bit above my pay-grade, but I always learn something or get to try a new open source/open web technology.

I also get to see many of my buddies on the open social web (AT Proto/Bluesky and ActivityPub) over video from across the web and engage with them all in real time.

The discussions are top notch and there is even a sense of a hallway chat area in the online software Johannes and Anca (the organizers) use.

They also use collaborative note taking, so even though the video/recordings are non-existent, there are great notes collaboratively made and later posted on the FediForum.org site after the event.

If you get a chance to make a FediForum, you really should attend. The tickets are affordable and the community is so nice!

TIL:

JSON-LD, used heavily in #ActivityPub, is a way of representing #RDF triplets.

Both Mastodon and Pixelfed seem to attach images as ActivityPub/ActivityStreams "type" = 'Document'.

I would have expected "type" = 'Image'.

'Document' isn't wrong. It is valid.

But, I would have expected the more specific type of 'Image'.

#ActivityPub #ActivityStreams #FediDev

I think it would be better if instead of Fediverse software outputting the following for ActivityPub/ActivityStreams Notes, Articles, etc:

"attributedTo": "mastodon.social/users/reiver",

It would instead output something more like:

"attributedTo": {
"id":"mastodon.social/users/reiver",
"type":"Person",
"name":"Charles",
"preferredUsername": "reiver",
"icon": {...},
"image": {...},
}

This way the Activity* document contains everything needed to render it.

Has anyone done a comparative analysis of various #activitypub implementations on the fediverse? Thinking adherence to protocol, extensions to vocabulary, databases used for persistence etc….

For those who have questions about #Holos. I've seen a lot written recently, and since the project is young, it's normal that things stay ambiguous or get misunderstood. This is a thread, with one post per remark most often read, and a direct answer.

As I had some time left, I decided to join to the session convened by Ben Pate on #E2EE #messaging over #ActivityPub. Albeit late participation, I was able to catch-up via notes and have the honor to hear insider information how #chat in #Fediverse gets into its shape.
